Q436-Input Signal Conditioner

Brand: Eurotherm

The Q436 is a DIN rail mount, potentiometer input signal conditioner with 1,800 Vdc isolation between AC power and the input/ output circuitry.

The input provides a constant voltage and is designed to accept any 3-wire potentiometer from 100 Ohms to 100 KiloOhms. 

The field configurable output is switch selectable providing a 0 to 5 V, 0 to 10 V, 0 to 1 mA, 0 to 20 mA or 4-20 mA DC signal.

Wide ranging, precision zero and span pots, used in conjunction with DIP switches, allow 80% adjustability of offset and gain to transmit a full scale output from any 20% portion of the potentiometer input.
